Synergistic insect control

Abstract

There is provided a method for the synergistic control of insects which comprises applying to the locus of a transgenic crop which produces an insect toxin a synergistically effective amount of a recombinant insect virus containing a vector which is highly virulent to said insect.

I claim:  
     
       1. A method for synergistic control of an insect which comprises applying to the locus, foliage or stem of a transgenic crop which produces an insect toxin a synergistically effective amount of a recombinant insect virus containing a vector which is highly virulent to said insect, wherein said recombinant virus is HzNPV, HzAalT, ETGdel or a combination thereof and wherein said transgenic crop is a crop plant which has been genetically altered to express  Bacillus thuringiensis  toxin. 
     
     
       2. The method according to  claim 1  wherein said transgenic crop is maize. 
     
     
       3. The method according to  claim 1  wherein said transgenic crop is cotton. 
     
     
       4. The method according to  claim 3  wherein said crop is NuCotn 33B. 
     
     
       5. The method according to  claim 1  where the synergistically effecting amount of said recombinant insect virus is about 1×10 10  OB/ha to about 1×10 13  OB/ha. 
     
     
       6. The method according to  claim 5  wherein the insect is Lepidoptera. 
     
     
       7. The method according to  claim 6  wherein the insect is  Helicoverpa zea.    
     
     
       8. The method of  claim 3  wherein the recombinant virus is HzAaIT. 
     
     
       9. The method of  claim 4  wherein the recombinant virus is HzAaIT. 
     
     
       10. The method of  claim 9  wherein the insect is  Helicoverpa zea .
